To all whom it 'may concern:

Be it known that I, Nonnen DEWAR MAC- enneon Yonne, a subject of the King,r of Great Britain, residing et Glasgow, Scotland, have invented a certain new and useiul Linear lileasure for Ropes, &c.,of which the following is a specification. This invention relates to a linear measure or devicev for measuring 'and indicatingthe continuous length of ropes, cords, Wires, tapes, rods and other materiel.

lu devices as at present generally in use for measuring the continuous length of cords, ropes and the like, the material being measured passes around a shear or drum whose rotary motion imparted through suitable gear to an indicator, and such linear 'measures have the disadvantages that the rope or the like is very liable to slip on the surface ot the drum and the length shown on the indicator of the device is true only for one diameter of rope or the like.

'l`he objeet oit' the presentinvention is to 'provide a linear measure lwhich accurately from this endless hand, is a suitable gear from which an indicator is operatethl, the motion of the rope brother matcriolbeiug Athus transini-'ttedto the endless band andthe motion of the band being tmnsmitted to the indicator. r

ln order-.that my invention'inay be clearly understood l have hereuntoappended eX- planatory drawings, wliere ;n:-w

- Figui-e1 is a front elevation of the measr urineV device andfFig. 2 shows the same With the :trontplate removed. Fig. 3 is a 'section vtaken on the line X3X3, of Fig/' 1 andi Fig. l a ysection taken on line rY--Y of Fig. l.

The endless band preferably consists of a series of links l which are movably con nected together by means of joint links 2 in such manner. that the teeth of a sprocket Wheel or, pinion 3 extend into spaces 4 left between the vjoint links 2 and thus allow the endless band to inevein one or theother `Specification of Letters Patent.

direction and rotetethe'v sprocket 4Whel or pinion 3. The links 1'. are rovided at their ends with recesses 5 Wherem the one end of the joint link 2 'is secured While the other end of the link 2 is fixed to the next link l together so as to form en endlessbnd. Esch side of thelik 1 -i's provided, with two pro# 'jectios 6,'1'?, and vsecured to'` or fitted in the top of the link is a' plate or pad 8. .In some dispensed with and' e suitable groove or recess may be formed 'in the" top of the link in lieu oit the plate or pad.

The endless band lis inclosed -in a suitable casing preferablyV consisting of a removable 11. Ihe removable front plete 9, is held in' position by means of screw bolts 12 or the like Which pass through distance piecesl 13 The side plates 11 rest,in suitable checks or recesses provided in the front end'baok plates and are constructed so as to l'avee plates-or pads 8 or the tops ofthelin'ks 1- extend or project. f

Secured 'to each', inner face of -the -`frontandI baokplates-9,`10, are races 14 and' 15 respectively, whichl are provided with lpro let'tbetxveen the projections 6, 7 of the links 1 audfornnng e dust4 excluding ldevice while allowing the endless band to rotate 'freely To facilitate and insure the `smooth and easy running of the endlessv band, balls 18 'links v1V and the raices 14, 15. y

of the material measured on; 'a 'suitably uated plate iXdtothe-outer face ofthe removable front plate 9, is operated from' erably consisting of the sprocket Wheel 3, which engages between the link joints' 2 and .and a Worin 21 secured to the` sprocket Wheel .shaft 22.' Meshing with the said worm 21 is 24, rotatablyittedin bearings 25, 26, Also lsecured to this shaft 24 is a Worm27`which front plate 9, back plate'lO and side platesy jections 16, 17, extend-ing, into the recesses are provided ivhich are'placed in ball bear-f rings formed 'in 'any suitable mannerbyithe The pointer 19 -which idicetesthe length j griidis rotated by the motion-fof the endless band,

`and so on, thus; all the links l are joined cases, if desired,.the plate ror pad 8 may be -I whereby Ythe vfront plate 9` and the' back plate 10 are kept at a suitnble'distance apart.

yup or recess at the top through Which-:the

between, the front and beck plates 9, 10. 7` i the endlessA band by intermediate gear, prefa Worm wheel 23 which is Ikeyed totd shaft engages with a Worm Wheel 28, 'the latter' being lkeyed to. a shaft '29 `to which: is se -cured a pinion Wheel 30 meshing with a Located inthe device is a niovahle platel or pad 34 (with or Without bearing rollers) which bears against the rope or other niater1al35 and presses same against the plates ,or pads 8 or the groovedoi recessed tops or' the links 1 et the endlessliand. rl`his pres-- sure-is produced by means of a spring or pressure device 36l which is fitted ou a spindle' 37 passing through a bracket 38 which is" secured t the hack plate l0 lijf Ineans'oi'ial screw .39' or its equivalenti. A handle 40,is fitted to one. end of the spindle 37, Whilethe other end is provided with an extension 4:1 'littedv in. a .recess in the plate or pad 34. A screw bolt 42 passes through the plate or padl 34 and the ,extension fil of the rod 37 and therebyr movably secures the latter to the plate or pad 34. This screw Vbolt 42 entendsthrough a slot or opening 43 the back1 plate l0, so as te allow of the plate or pad, 3 i`fbeing moved or operated hy means of the, handle 40, against the action of the spring 38,` for the purpose of introducing` or removing the rope 35, or other material being measured. When the handle 40 is in its working position the plate or pad 34 ispressed a ainst the rope'3f5 or other material and t e latter is thereby pressed against'thelinovahle endless band so that, as the rope or other material is pulled fon Ward, the endless hand is rotated thereby rotating the sprocket Wheel 3 andworm and Worin Wheel gearing 21, 23, 27, 23, and consequently also `the pointer 19 on the shaft 32 thus indicating on the graduated plate 20 the length of the material measured.

Having now fully described my ihren-- tion, what I claim and desire to secure hy "Letters Patentist*` 1. A device for measuring the length of an article (suchas a rope, cord, rod, Wire or tape) comprising an endless traveling hand, an endless hearing race, haring a straight uiiyielding portion therein, for the inner surface 'of the band, ineens for press' ing the article being measured against the outer surface of the hand which hand is supported, and held in a straight line, by the said straight surface, and indicator mechanism automatically operated from the traveling hand.

Q. A devicefoi measuring the length of an article (such as a rope, cord, rod, Wire or tape) comprising an outer casing made in parts, an endless traveling hond, an endless bearing' race between the parts of the casing and haring a straight uiiyielding portion therein, for ti e tnner surface of the hand, means for pressing the article being measured against the outer surface of the hand which hand is supported, und held iii a straight line, by the said straight surface, and indicator mechanism automatically operzited from the traveling liand.
